What is a good Hash Function?
...eed to worry about how reversible or hackable the algorithm is... SHA-1 or AES is completely unnecessary for this, you'd be better off using a variation of FNV. FNV achieves better dispersion (and thus fewer collisions) than a simple prime mod like you mentioned, and it's more adaptable to varying i...

JavaScript regex multiline flag doesn't work
...lt.
The bad news is that it does not exist in JavaScript (it does as of ES2018, see below). The good news is that you can work around it by using a character class (e.g. \s) and its negation (\S) together, like this:

So in your case the regex would become:
/<div class="box-content-5"&...

-p is for a password (optional)
-w is a the source directory....
